Color filter and production method thereof as well as liquid crystal panel

Abstract

The invention discloses a color filter and a production method thereof as well as a liquid crystal panel. The color filter comprises a substrate and a black matrix, a gap grain and a color filtering layer which are formed on the substrate, wherein the black matrix and the gap grain are of an integrated structure; the thickness of the black matrix is more than that of the color filtering layer; and the color filtering layer is used for adding color ink into the black matrix on the substrate according to an ink jet printing method and curing the color ink. In the color filter provided by the invention, the black matrix and the gap grain are of the integrated structure by exposing and developing a black film on the substrate, thereby simplifying the production method of the color filter. In the color filter, the color filtering layer is produced according to the ink jet printing method, so that the height of the black matrix is unlimited during the production process for forming the color filtering layer, the existing material can be used for producing the black matrix and the gap grain, and the production yield of the color filter is increased.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter, a manufacturing method of the color filter and a liquid crystal panel. Background technique [0002] Liquid Crystal Display (LCD) is a flat panel display device (Flat Panel Display, FPD) that uses the characteristics of liquid crystal materials to display images. Compared with other display devices, it has thinner, lower driving voltage and lower power consumption. Consumption and other advantages, has become the mainstream product in the entire consumer market. The liquid crystal display panel is composed of a color filter and a TFT array substrate, and gap particles are arranged between the two to form a gap for liquid crystal injection. The interstitial particles are generally disposed on a color filter. [0003] Such as figure 1 As shown, the existing color filter includes a substrate 101, a black matrix 102 disposed on the substrate 101, a c...

AI Technical Summary

Problems solved by technology

Therefore, in order to meet the requirement of the gap between the two substrates, unless the black matrix 102 and the interstitial particles 105 are made of a new material with a very high light sensitivity, the new material with a very high light sensitivity will also vary depending on the machine in the actual process. Unstable black film thickness due to energy difference, which will increase the defective rate of subsequent processes
